Alecys


A hermit priest encountered by Perceval in a forest, beating a giant cross with a rod. Perceval refrained from punishing this blasphemy only because Alecys looked like a priest.

He later discovered that Alecys hated the cross because Christ had died on one, just as one would hate a weapon which had killed one’s relative.
